40V 191982 Docket No. 50-322 MEMORANDUM FOR: Thomas M. Novak, Assistant Director for Licensing. Division of Licensing FROM:
L. S. Rubenstein, Assistant Director for Core and Plant Systems, Division of Systems Integration i
SUBJECT:
RPS MG SET INTERNAL MISSILE CONCERN - SHOREHAM NUCLEAR POWER STATION, UNIT 1 At your request, we have reviewed the applicant's letter dated August 31, 1982, which includes an enclosure entitled "RPS MG Set Missile Analysis."
Eval'uation of internally generated missiles is the responsibility of the Auxiliary Systems Branch. The applicant's letter was submitted in response to the agreement reached between the applicant, staff, and intervenors for resolution of Shoreham Hearing Contention SC 31/ SOC 19g and the concern identified in I&E Inspection Report 50-322/82-08.
The agreement in part required the applicant to submit an evaluation of the RPS motor generator
. set missile concern and the staff to notify the Parties and the Board upon acceptance of the submittal. The agreement also allows the intervenors to submit a new contention if they disagree with the staff's resolution.
Our evaluation is as follows:
The applicant's analysis postulated a single missile generated from the RPS motor generator set flywheel. The area affected by the assumed trajectory of the missile was examined to determine if redundant safety related equipment could.be impacted by the single missile source. -The affected area contains cabling, a water pipe line, and a ventilation air duct. The applicant verified that sufficient separation exists to preclude damage to more than one train of cabling for safety related equipment.
Potential flooding in the MG set room resulting from impact and rupture of a nonessential domestic water supply line is prevented by automatic-closure of a pressure control valve due to the resulting loss of pressure in the line. The only other potential target is a ventilation air supply duct for the relay room, computer room, and switchgear room. Rupture of this duct results in only a partial loss of air flow.
In addition, temperature monitors in safety related areas will provide the operator with room temperature status and time to take any action necessary to assure proper i
temperature for equipment operation.

[ Thomas M. Novak Based on the above, we conclude that the applicant has satisfactorily demonstrated that in the unlikely event of missile generation from the RPS MG Set, sufficient separation and other plant features are available to preclude adverse safety consequences and thus safe shutdown of the plant is not affected.
We have discussed the above evaluation with MTEB and they conclude that the applicant's analysis is conservative.
